Flashlight therapy is the process of beating someone with a large flashlight eg Mag-Lite to help them come to their senses. Often used by police officers. Can be prescribed by doctors when they become irate with annoying patients.

- James bought a large 4x D-cell anodised Mag-Lite to help him see in the dark, and also to help others "see the light".
